Art. 14. A neutral Power may authorize the passage over its territory of the sick and wounded belonging to the belligerent armies, on condition that the trains bringing them shall carry neither personnel nor war material. In such a case, the neutral Power is bound to take whatever measures of safety and control are necessary for the purpose. The sick or wounded brought under the these conditions into neutral territory by one of the belligerents, and belonging to the hostile party, must be guarded by the neutral Power so as to ensure their not taking part again in the military operations. The same duty shall devolve on the neutral State with regard to wounded or sick of the other army who may be committed to its care.
